Moles: Concerns About Changes and Skin Health - Dermatology

Mole issues


Due to the black moles on my back, it's difficult to take photos, so I can only describe them.
There are two located in different areas, each about the size of the tip of a nipple, but they are not very raised.
When touched, they feel slightly elevated.
I first noticed them when I was in kindergarten, and I have been aware of their presence since then.
They usually do not hurt, and there is no pain when they are rubbed or brushed against.
However, pressing or scraping them with my fingernail causes a stinging sensation.
Is this a cause for concern? Could they undergo any changes?

Without actually seeing the lesion, it is impossible to determine.
If it is very concerning, please seek medical attention as soon as possible.

When it comes to understanding moles and their potential implications for skin health, it's essential to approach the topic with a combination of awareness and caution. Moles, or nevi, are common skin growths that can vary in size, color, and texture. They are typically benign, but changes in their appearance or sensation can raise concerns.

From your description, it seems you have two moles on your back that have been present since childhood. The fact that they have not changed significantly over time and do not cause pain during normal activities is a positive sign. However, the sensitivity you experience when pressing on them could indicate that they are somewhat raised or that there is a degree of nerve sensitivity in that area.
It's important to monitor moles for any changes, as certain alterations can be indicative of potential issues. Key signs to watch for include:
1. Asymmetry: If one half of the mole does not match the other half in shape or color.

2. Border Irregularity: Moles with jagged, notched, or blurred edges may be concerning.

3. Color Variation: Moles that have multiple colors or shades (such as brown, black, tan, red, white, or blue) should be evaluated.

4. Diameter: Moles larger than 6mm (about the size of a pencil eraser) warrant further examination.

5. Evolving: Any change in size, shape, color, or elevation, or any new symptoms such as bleeding, itching, or crusting, should be assessed by a healthcare professional.

Given that you have not experienced any significant changes in your moles over the years, it is likely that they are benign. However, the fact that you feel pain when pressing on them could be worth discussing with a dermatologist. They can perform a thorough examination and may recommend a biopsy if there are any concerns about atypical features.

In terms of skin health, maintaining a good skincare routine is essential. This includes:
- Sun Protection: Always apply sunscreen with a high SPF to protect your skin from UV damage, which can lead to changes in moles and increase the risk of skin cancer.

- Moisturization: Keeping your skin hydrated can help maintain its barrier function and overall health.

- Regular Check-ups: Schedule regular skin examinations with a dermatologist, especially if you have a family history of skin cancer or if you notice any changes in your moles.

If you have a history of skin issues or if you are particularly concerned about your moles, it may be beneficial to seek a professional opinion. Dermatologists can provide personalized advice based on your skin type, medical history, and any specific concerns you may have.

In summary, while your moles may not currently present a problem, staying vigilant and proactive about skin health is crucial. Regular monitoring, sun protection, and professional evaluations are key components of maintaining healthy skin and addressing any potential issues early on.
